I've tried using the fix in https://tex.stackexchange.com/a/492197/193767
in order to make TikX's remember picture feature usable, Code below, just
in case:
\unprotect% This fixes the present
bug\unexpanded\def\pdflastxpos{\numexpr\clf_lastxpos\relax}\unexpanded\def\pdflastypos{\numexpr\clf_lastypos\relax}%
This might be needed if you run PGF 3.1.3% see
https://github.com/pgf-tikz/pgf/issues/675\def\XC@tgt@mod#1{#1}\def\XC@sdef#1#2{\edef#1{#2}}\protect\usemodule[tikz]\starttext\starttikzpicture[remember
picture]
\node (A) {Node 1};\stoptikzpicture
Hi world\starttikzpicture[remember picture]
\node (B) {Node
2};\stoptikzpicture\starttikzpicture[overlay,remember picture]
\draw (B) --++(0,0.5) -| (A);\stoptikzpicture\stoptext
However, the following appears:
l.1 6
120806
\lastxpos ->\clf_lastxpos
<write> \noexpand \pgfsyspdfmark {pgfid1}{\the \lastxpos
}{\the \lastypos }
<inserted text>
}\endwrite
<argument> \shipoutscratchbox
\page_shipout_box #1->\clf_shipoutpage #1
\relax \setbox #1\emptybox \global ...
...
l.20 \stoptext
I use LuaTeX 1.10 7127 + ConTeXt MkIV 2019.03.21 21:39 (TeX Live version),
in case this helps. Is another fix necessary? A Metapost alternative would
be fine, too.
